• What is the cause and solution for SAP error message CN389 - Actual costs and/or actual revenues exist: Object class cannot be changed ?

  The SAP error message CN389 indicates that there are actual costs and/or actual revenues associated with a particular object, and as a result, the object class cannot be changed. This typically occurs in the context of controlling (CO) and project systems (PS) within SAP, where object classes are used to categorize cost objects.
  Cause:
  
  Actual Costs/Revenues Exist: The primary reason for this error is that there are already posted actual costs or revenues against the cost object (e.g., internal order, project, etc.). When actual postings exist, the system prevents changes to the object class to maintain data integrity and consistency.
  Object Class Restrictions: Certain object classes may have specific rules or restrictions that prevent changes once actual postings have been made.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review Actual Postings: Check the actual costs and revenues associated with the object. You can do this by using transaction codes like KOB1 (for internal orders) or CJI3 (for project-related costs) to see the postings.
  
  
  Create a New Object: If changing the object class is essential, consider creating a new cost object with the desired object class and transferring the relevant costs and revenues to the new object. This may involve:
  
  Creating a new internal order or project.
  Using transfer postings to move costs from the old object to the new one.
  
  
  
  Consult with Finance/Controlling Team: If you are unsure about the implications of changing the object class or transferring costs, consult with your finance or controlling team. They can provide guidance on the best approach based on your organization's policies.
  
  
  Use a Custom Program: In some cases, organizations may have custom programs or transactions that allow for the modification of object classes under specific conditions. Check with your SAP support team to see if such options are available.
  
  
  SAP Notes and Documentation: Check for any relevant SAP Notes or documentation that may provide additional insights or solutions specific to your version of SAP.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  KOB1: Display Actual Line Items for Orders
  CJI3: Display Actual Costs for Projects
  KO03: Display Internal Order
  CJ20N: Project Management
  
  
  Object Class: Understand the implications of different object classes and how they relate to your organization's cost accounting practices.
  Data Integrity: Recognize the importance of maintaining data integrity in financial reporting and controlling processes.
  
  By following these steps, you should be able to address the CN389 error and proceed with your SAP activities.
